Description
Technical field
The present invention relates to technical field of valve manufacturing, is a kind of adjusting rod structure of Novel regulating valve specifically.
Background technology
Valve is for being opened and closed pipeline, control flow direction, regulation and the parameter of control pumped (conveying) medium（Temperature, pressure and flow）
Pipeline fittings.According to its function, shut-off valve, check-valves, regulating valve etc. can be divided into.Valve is the control in fluid delivery system
Part, there is cut-off, regulation, water conservancy diversion, prevent the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief.
Valve can be used for controlling empty gas and water, steam, various Korrosionsmediums, mud, oil product, liquid metal and radioactivity
The flowing of all kinds fluid such as medium.Valve is also divided into cast iron valve, cast steel valve, stainless valve according to material（201、
304th, 316 etc.）, chrome-molybdenum steel valve, Chrominm-molybdenum-vanadium steel valve, dual phase steel valve, Plastic valve, nonstandard customized valve etc..
Regulating valve also known as control valve, in industrial automation process control field, exported by receiving regulation unit
Control signal, go to change the final control element of rate-of flow, pressure, temperature, the technological parameter such as liquid level by power operation.
Typically it is made up of executing agency and valve.If pressing stroke feature, regulating valve can be divided into Direct Travel and angle stroke；Match somebody with somebody by it and hold
The power that row mechanism uses, pneumatic control valve, electric control valve, three kinds of hydraulic adjusting valve can be divided into；By its function and characteristic
It is divided into three kinds of linear characteristic, equal percentage characteristics and parabolic characteristic.Regulating valve is applied to empty gas and water, steam, various corrosivity
The media such as medium, mud, oil product.English name：Control valve, position number generally FV beginnings.Regulating valve common classification：Pneumatically
Regulating valve, electric control valve, hydraulic adjusting valve, direct-operated regulator, but existing regulating valve is there is significant limitation,
The needs of modernization industry production can not be met.
The content of the invention
It is an object of the invention to provide a kind of adjusting rod structure of Novel regulating valve, can with new regulating valve,
Meet different industrial production needs.
In order to achieve the above object, the present invention is as follows using technical scheme：
A kind of adjusting rod structure of Novel regulating valve, is made up of connecting portion and valve rod, and connecting portion is divided into three parts point from top to bottom
Not Wei first connecting portion, second connecting portion and the 3rd connecting portion, first connecting portion, second connecting portion and the 3rd connecting portion two-by-two it
Between be fixed together using welding procedure, valve rod extends outward inside the 3rd connecting portion, valve rod and the 3rd connecting portion
Junction is provided with welding briquetting, and taper bolt is provided with the outside of the pars intermedia of valve rod.
Further improvement of the present invention, the internal diameter of the 3rd connecting portion are more than the internal diameter of first connecting portion, the 3rd connecting portion
Internal diameter is less than the internal diameter of second connecting portion.
Further improvement of the present invention, the height of the height of first connecting portion, the height of second connecting portion and the 3rd connecting portion
Ratio between degree is 1:2:1.5.
The height ratio of further improvement of the present invention, the height of valve rod and whole adjusting rod structure is 1:3.
Further improvement of the present invention, valve rod external diameter are 1 with taper bolt external diameter ratio:1.5.
Further improvement of the present invention, valve rod bottom use fillet design.
Beneficial effects of the present invention：The present invention is acted in regulating valve, simple in construction, rationally distributed, has certain lead to
With property and sealing.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
In figure, 1- first connecting portions, 2- second connecting portions, the connecting portions of 3- the 3rd, 4- welding briquettings, 5- valve rods, 6- circular cones
Pin.
